The Buick LaCrosse comes in three models. The CX and the more luxurious CXL come with a 3.8-liter overhead-valve V6 rated at 200 horsepower. The performance-oriented CXS comes with 3.6-liter V6 with modern double overhead cams and variable valve timing that develops 240 horsepower.
The CX ($22,935) comes with cloth upholstery and manually operated air conditioning. Standard features for all models include tilt wheel, six-way power driver's seat, programmable power locks with remote keyless entry, power windows and mirrors, leather-wrapped shift knob, and a six-speaker AM/FM/CD sound system. All models also come standard with OnStar and a one-year subscription.
